A saw bow with a closing tensioner characterized by comprising a bridge support in tubular profile of oval section whose support in its rear branch has a joint for a lever capable of folding over it partially covering it and with the particularity that this lever manually operated is articulated with eccentricity to a tension rod attached to an intermediate arm inserted in the internal part of the bow itself and in the vicinity of the rear branch by arranging this intermediate arm of a retaining claw for one of the ends of the saw blade that is supported on the front by another adjustable by threading all in such a way that the maximum displacement of the eccentric of the tension rod by the closing lever coincides at a point immediately before the total retraction so that once this the mechanism is irreversible by its own means.
